  • GlyPID: N-glycosylation peptide identification tool[link]


    GlyPID 2.0, a software tool for accurate characterization of protein glycosylation through a combination of the following techniques.

    • Accurate precursor ion mass calculated using THRASH–based deisotoping methods
    • A CID score calculated from Collision-Induced Dissociation (CID) spectra, similar to previous version of GlypID [1]. The model is based on spacing between fragment peaks indicative of glycan fragmentation.
    • A new HCD score calculated from High-energy C-trap Dissociation (HCD) spectra scoring technique based on the presence of characterestic glycan peaks. HCD is available on the LTQ Orbitrap XL.

  • MultiGlycan: Glycan profiling tool (MALDI/LC-ESI)[link]


    • MultiGlycan helps user to gather glycan profile information from LC-MS Spectra. It also reports quantity of specific glycan composition. We've developed two different versions of MultiGlycan: one for MALDI, and the other one for ESI. The MALDI version deconvolutes regular and overlapping glycans using simple model matching; The ESI version extracts glycans using adduct information.
